SCO OS 6.0 with MP3 breaks Roundtree Accounting
I installed MP3 on a client's 6.0 system but had to
remove it (by restoring the root file system from the
nightly backup) as the RoundTree accounting application
failed to run.
This is the error message that comes up when you try to
run the system:
Invalid Environment Variable "AUSER".
Please correct and re-try.
Exiting to Operating System.
In the MP3 release notes there is a XENIX compatibility section
that states in part:
1. A previously installed Xenix application that uses semaphores may
fail immediately after upgrading to MP3 because of a change in the
way Xenix semaphores are implemented. Previously, the xrun
emulator simulated Xenix semaphores via System V semaphores, using
regular files that contained information about the semaphore
properties. As noted above, MP3 eliminates that implementation in
favor of a direct kernel-level implementation of Xenix semaphores.
If such an application failure is encountered after installing
MP3, application functionality can usually be restored by shutting
down the application, deleting the old semaphore files, and then
restarting the application. In a few cases, it might be necessary
to reinstall the application.
How do I identify these semaphor files? No hint is given on how to find them.
Read on if interested to see the proof that this is a compiled Xenix binary.
The problem is a compiled Xenix application as indicated by access time on
To test if the /u/advnt/progs/ADV executable uses the xrun emulator
I issued the following commands:
Note that l -lu lists the last time the file is accessed instead of the
date the file was modified.
# l -lu /bin/xrun
-r-xr-xr-x 1 bin bin 150332 Aug 22 21:47 /bin/xrun@ Last
Fri Aug 22 22:03:26 CDT 2008
# cd /u/advant/progs
# ./ADV Then exit: I just got to the login screen and then exited.
Immediately issuing the l -lu /bin/xrun after exiting ADV:
# l -lu /bin/xrun
-r-xr-xr-x 1 bin bin 150332 Aug 22 22:04 /bin/xrun@ Last

Have you tried OSS710a, the Xenix Compatibility update at:
If no, please do.
If you are still experiencing problems then SCO do provide an alias
